From Daniel Ginsburg:

draft-ietf-isis-ext-eth specifies an extension to current Ethernet Frame
specifications for hardware and frame format to support payloads greater than
1500 Bytes for Type interpretation and Length interpretation frames.

The extension introduced by draft-ietf-isis-ext-eth is currently used by Cisco
Systems' IS-IS routing protocol implementation when running IS-IS over Ethernet
links with large MTU.
